DESCRIPTION
ISO 21687:2007
ISO 21687:2007 specifies a method for the determination of the density of green and calcined petroleum coke and similar solid materials (e.g. electrodes). ISO 21687:2007 is also suitable for hydrocarbons with a high-temperature boiling range and for other solid materials. This method is not suitable for graphitized material.
